As shown in fig. 2 to 4, an embodiment of the present invention provides a locking type ground clip fixing device, including: the device comprises a pull rod 1, a fixed part, a movable part, a crank arm 10 and a connecting rod 6, wherein the fixed part comprises an upper fixed section 9 and a lower fixed section 2 which are arranged in parallel and a vertical section 3 which is connected with the right ends of the upper fixed section 9 and the lower fixed section 2; the movable part can comprise a clamping section 5, a locking section 12 is formed at the left end of the clamping section 5, the right end of the clamping section is connected with the vertical section 3 in a sliding mode, an opening for placing a lead is formed between the clamping section 5 and the upper fixing section 9, and a locking hole 13 is formed in the locking section; the crank arm 10 is rotatably connected with the left end of the upper fixing section 9, the left end is provided with a locking piece 11 matched with a locking hole 13 of the locking section 12, and the right end is provided with a sliding groove 8; one end of the connecting rod 6 is inserted into the vertical section 3 to be connected with the clamping section 5, and the other end of the connecting rod is in sliding connection with the sliding groove 8 through a sliding block 7; the pull rod 1 penetrates through the lower fixing section 2 to be connected with the clamping section 5, and a spring 4 is arranged between the pull rod and the movable piece; after a lead is placed in the opening, the pull rod 1 is released, the movable part drives the connecting rod 6 to move upwards, and then the crank arm 10 is driven to move downwards, so that the locking piece 11 is inserted into the lock hole 13 to be clamped together, and locking between the fixed piece and the movable part is achieved.
In the embodiment of the invention, the lower fixing section 2 can be provided with an opening through which the pull rod 1 passes. The pull rod 1 passes through the opening to be connected with the movable piece. The lower end of the pull rod 1 may be provided with a structure suitable for being pulled by fingers, for example, the lower end is formed in a T-shaped structure. One end of the spring 4 is sleeved outside the pull rod 1 and is positioned between the clamping section 5 and the lower fixing section 2, and the spring is used for enabling the movable part to move upwards through elasticity when the pull rod 1 is released.
In the embodiment of the present invention, the crank arm 10 and the upper fixing section 9 may be rotatably connected by a support shaft, and in particular, the crank arm 10 may be connected at an end of the left end of the upper fixing section 9 at a position of about one sixth length by the support shaft. In one example, in order to enable the crank arm 10 to rotate along the upper fixing section 9, an end portion of a left end of the upper fixing section 9 may be formed with an inclined surface inclined downward to the right to form a rotation fulcrum suitable for the crank arm to rotate.
As shown in fig. 2 and 3, in the embodiment of the present invention, the locking section 12 may be disposed obliquely downward along the left end of the clamping section 5, for example, may be obliquely downward at 15 ° to 30 °, that is, the angle between the locking section and the clamping section 5 may be 15 ° to 30 °. Furthermore, the locking section 12 may be a cylindrical structure, and preferably, may be a cylindrical structure with a diameter gradually decreasing from top to bottom. In addition, the locking section 12 is further provided with a stopping portion 14 formed to protrude upwards on a side close to the clamping section 5, and when the locking member 11 is inserted into the locking hole 13, the stopping portion 14 contacts with the inclined surface to cooperate with the fixed member and the movable member to form a fixed opening for fixing the wire. The lock member 11 may be formed as a cylindrical circular truncated cone adapted to be inserted into the lock hole 13 and lock the lock hole 13. In addition, a flexible anti-slip pad can be arranged on the locking piece 11 to increase the friction with the locking hole 13, so that the locking piece can be connected with the locking hole 13 more firmly.
