Specifically, the setting of the unscrewing limiting ring 44 is used for limiting the unscrewing spring 43 from being forced to be pulled out from the unscrewing hole 104 when the unscrewing spanner block 42 is moved out of the unscrewing bolt 41, that is, ensuring that the unscrewing spring 43 can normally play a due elastic function in the long-term frequent spanner block 42 screwing use process.
It should be noted that, when the tightening lock assembly 30 is in the working state, the loosening lock assembly 40 is in the non-working state; when the unscrewing lock assembly 40 is in the active state, then the tightening lock assembly 30 is in the inactive state. For example, when the tool rod 300 needs to be screwed down, the screwing down pulling block 32 is pulled to enable the screwing down lock tongue 31 to be in an automatic telescopic state in the screwing down piece hole 102, and the unscrewing pulling block 42 is pulled to enable the unscrewing lock tongue 41 to be retracted into the unscrewing hole so as to avoid interference to the tool rod 300; conversely, when the tool rod 300 needs to be unscrewed, the unscrewing spanner block 42 is pulled to enable the unscrewing bolt 41 to be in an automatic telescopic state in the unscrewing piece hole 104, and the tightening spanner block 32 is pulled to enable the screwing bolt 31 to be retracted into the tightening hole, so that interference on the tool rod 300 is avoided; thus, the tightening and loosening of the bolt 31 and 41 do not interfere with each other, and the normal tightening and loosening of the tool bar 300 can be ensured.
Wherein the only structural difference between the tightening and loosening lock assemblies 30, 40 is that the reverse incline 312 is oriented differently than the forward incline 412.
Further, as shown in fig. 7 and 10, the first arc member 10 includes a first upper arc plate 11 and a first lower arc block 12 fixedly connected with the first upper arc plate 11, for example, by fastening a fastener, where the tightening member hole 102 and the loosening member hole 104 may be formed on the first upper arc plate 11 or the first lower arc block 12, and the first lower arc block 12 may have multiple pieces; likewise, the second arc member 20 includes a second upper arc plate 21 and a second lower arc block 22 fixedly connected to the second upper arc plate 21, for example, the tightening member hole 102 and the loosening member hole 104 may be formed on the second upper arc plate 21 or the second lower arc block 22 through fastening connection by fasteners, and the second lower arc block 22 may have multiple pieces.
Further, as shown in fig. 8 to 9, the first end of the first upper arc plate 11 is hinged to the first end of the second upper arc plate 21 by a pin 108, so that the first upper arc plate 11 and the second upper arc plate 21 can rotate around the pin 108 as a rotation axis. Preferably, a fixed buckle 106 is provided at the second end of the first upper arc plate 11, and a movable buckle 107 is provided at the second end of the second upper arc plate 21, and when the second end of the first upper arc plate 11 is abutted with the second end of the second upper arc plate 21, the movable buckle 107 is buckled on the fixed buckle 106, thus forming an integral fixing mechanism 100.
In this embodiment, as shown in fig. 1 to 5, the driving mechanism 200 further includes a fixed seat 70, a movable seat 71, a movable nut 72, and a screw 80, where the movable nut 72 is in threaded connection with the screw 80, one end of the fixed seat 70 is fixedly connected with one end of the screw 80, the fixed seat 70 is hinged to the other end of the fixed arm 50, the movable seat 71 is sleeved on the periphery of the movable nut 72, and the movable seat 71 is hinged to the other end of the movable arm 60. Specifically, when the screw 80 is rotated, the moving nut 72 in threaded connection with the screw 80 moves linearly with the screw 80 as an axial direction, and since the movable seat 71 is sleeved on the periphery of the moving nut 72, the movable seat 71 moves along with the moving nut 72, and the movable seat 71 drives the movable power arm 60 to rotate relative to the fixed arm 50, and since the movable clamping member 61 provided on the movable power arm 60 is fixedly connected with the fixed mechanism 100, the fixed mechanism 100 can be driven to rotate clockwise or counterclockwise by the movable clamping member 61.
In this embodiment, as shown in fig. 1 to 5, the driving mechanism 200 further includes a driving member 90, where the driving member 90 is connected to the other end of the screw 80 to drive the screw 80 to rotate. For example, the driving member 90 is a torque handle or an electric wrench. Specifically, the torque handle or the electric wrench is adopted as the driving piece 90 to drive the screw 80 to rotate, so that the torque of the screw 80 can be set, and the torque of the tool bar wrench is set, so that the torque of the tool bar wrench can be quantized, and the phenomenon of loosening or loosening too much in the screwing process of the tool bar 300 is avoided.
In this embodiment, as shown in fig. 4 to 5, an arc-shaped guide rail 62 is disposed at the top of the movable clip 61, and an arc-shaped guide groove 52 matched with the arc-shaped guide rail 62 is disposed at the bottom of the fixed clip 51. Specifically, when the movable arm 60 drives the movable clamping member 61 to rotate, the arc-shaped guide rail 62 is matched with the arc-shaped guide groove 52, so that the movable clamping member 61 can rotate relative to the fixed clamping member 51, the fixed clamping member 51 clamps the amplitude transformer 400, the fixing mechanism 100 fixedly connected with the fixed clamping member 51 clamps the tool rod 300, and when the tool rod 300 rotates along with the movable arm 60, the tool joint can rotate relative to the amplitude transformer 400, so that screwing or tightening of the tool rod 300 can be realized.
In this embodiment, as shown in fig. 4 to 5, an upper arc-shaped groove 53 is provided at a side edge of the top of the fixing clip member 51, and an upper pressing block 64 having an end extending into the upper arc-shaped groove 53 and a shape adapted to the upper arc-shaped groove 53 is fixedly connected to the top of the movable arm 60; the side edge of the bottom of the movable clamping piece 61 is provided with a lower arc-shaped groove 63, and the bottom of the fixed arm 50 is fixedly connected with a lower pressing block 54, the end of which extends into the lower arc-shaped groove 63 and the shape of which is matched with the lower arc-shaped groove 63. Specifically, the upper pressing block 64 is provided to restrict upward movement of the fixed clip member 51 of the fixed arm 50 with respect to the movable clip member 61, and similarly, the lower pressing block 54 is provided to restrict downward movement of the movable clip member 61 of the movable arm 60 with respect to the fixed clip member 51. The upper arc-shaped groove 53 is arranged on the side edge of the top of the fixed clamping piece 51 and is matched with the upper pressing block 64, so that interference between the upper pressing block 64 and the fixed clamping piece 51 can be avoided when the upper pressing block 64 rotates along with the movable clamping piece 61; similarly, the side edge of the bottom of the movable clamping piece 61 is provided with the lower arc-shaped groove 63 to be matched with the lower pressing block 54, so that interference between the lower pressing block 54 and the movable clamping piece 61 which rotates can be avoided, and the design is ingenious as a result, and the practicability is strong.
In this embodiment, the two hinged parts may be hinged by a pin. The two parts fixedly connected with each other can be locked and connected by a fastener.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
