Description of the new type: [Technical field to which the new type belongs] This creation is related to power tools, especially a quick release joint for a power tool. 5 [Previous technology] According to the past, when operating electric tools such as electric drills, in order to cooperate with drilling circular holes of different sizes, operators often had to constantly change the tools used by electric tools; while general electric tools are replacing tools, A chuck wrench is used to loosen or tighten the three claws of the chuck of the power tool to achieve the purpose of changing tools. However, the chuck wrench is used to lock the tool to the chuck. The operation method is easy to cause the tool to idle during use due to improper locking, and each time the tool is replaced, the operator must rotate forward and backward, so it is still inconvenient to use. In addition, the chuck wrench As part of 5 tools, it is necessary to re-purchase because 5 operators have lost them. [New content] The main purpose of this creation is to provide a quick release for electric work.

The base rod has a concave portion. When the displacement member moves to the first position, the concave portion is connected with the displacement portion. Corresponding hole in the barrel; and at least 5 = I tight =, can be movably arranged in the receiving hole in the barrel, the pressing member is pressed by the base buckle and part of the body protrudes from the socket hole A peripheral wall; and a spring element provided on the rod portion and pushing the displacement element, the elastic element is used to provide the displacement element with a returning force for moving toward the second position. 10 [Embodiment] Yijing refers to the first to third figures, which is a schematic diagram of the state of the combination of a quick release joint (1) and a cutter (10) used in the creation of power tools. The cutter (10) can be a rotary saw Or a drill bit, etc., which has a shank rod (⑴) with a hexagonal cross section, and a ring groove (111) is provided at the end of the shank (11). The quick-release joint (1) mainly includes a cylindrical body (20), which is provided with a barrel portion (21) and a rod portion (22) along its axial direction. The barrel portion (21) has a socket hole (211), the cross-sectional shape of which corresponds to the cross-sectional shape of the shank (11) of the cutter (10) and is hexagonal, and is used for the shank of the cutter (10) ( 11) Insertion; the two guide holes (212) are respectively located at the 20 side of the socket hole (211), and are parallel to the socket hole (211) and pass through the two end faces of the tube portion (21), And two accommodation holes (213) communicate with an inner peripheral wall of the guide hole (212) and the socket hole (211), respectively. The two accommodation holes (213) are tapered and have a large diameter end (214) for conduction. The outer peripheral wall of the cylindrical portion (21) and a small diameter end (215) communicate with the inner peripheral wall of the sleeve hole (211). The rod part (22) has an inner section (221) connecting the M261341 body (20) and located between the two guide holes (212), and an outer section (225) connecting the inner section (221) Wherein, the shaft of the inner section (221) near the outer section (225) has a flange (222). In actual production, the inner section (221) has a ring groove (223) and uses a C-type A buckle (224) is embedded in the ring groove (223) to form 5 the flange (222), or the flange (222) can also be sleeved on the inner section by a plate in a tight fit ( 221), the replacement of these structures shall be regarded as the equivalent implementation of this creation. Furthermore, it is specifically explained here that the outer section (225) is also a hexagonal cylinder, which can be embedded in a drive unit of one of the aforementioned electric tools to drive the quick release joint (1) as a whole at high speed, however The focus of this non-genuine work is not detailed here. A quick release group (30) includes a displacement member (31), two base rods (32), and a pressing member. In the embodiment, the two pressing members are two round beads (33). Wherein: the displacement member (31) is in the shape of a circular plate, and has a perforation (311) in the center, and two engagement holes (312) are provided on both sides of the 15 perforation (311), and the displacement member (31) passes through the perforation.孑 L (311) is sleeved on the shaft (22) of the body (20) and is located on the inner section (221), so as to move along the shaft (22) in a position close to the cylinder (21). A position (shown in the third picture) and a second position (shown in the fifth picture) near the flange (222) slide back and forth. 2 The shafts of the two base rods (32) are respectively pivoted in the two guide holes (212) of the barrel portion (21), and the-ends thereof are connected to the displacement member (31) in a tight fit manner. ): The joint hole is), driven by the displacement member. In addition, the two base talents (32) each have a ring-shaped recess (321) near the other end, and the displacement member (31) When moved to the first position, the recess (cut) will correspond to the receptacle (213) of the tube M261341 (21). The two bead bodies (33) are respectively provided in one of the accommodation holes (213) of the cylindrical portion (21), and the diameter of the two bead bodies (33) is smaller than the small diameter end (215) of the accommodation hole (213). Between a base rod (32) and the socket hole (211), and the ball body (33) is pressed by the 5 base rod (32), and a part of the body protrudes from the socket hole (211) Inner peripheral wall. An elastic element is a spring (40) in this embodiment, and the spring (40) is sleeved on the rod portion (22) on the inner section (221), and one end thereof pushes the displacement member (31), and the other end pushes the flange (222) to provide the restoring force of the displacement member (31) moving toward the first position. With the above structure, the operation method of this creation is as follows: 15 Refer to the fourth ®, when the cutter ⑽ is to be installed, the operator holds the displacement member (31) of the quick release group (30) with his hand, and the displacement member ( 31) Move to the first position 'and cooperate with the fifth figure' At this time, the concave portion (Π) of the two base rods (32) is opposite to the two receiving holes (213) of the body⑽tube portion⑼, and the two round beads The body (33) is in a movable state, and then the tool ⑽ (shank rod 嵌) is embedded in the socket hole as shown in the first and third illustrations of 'connecting and continuing. The operator only needs to release the position mm' The lion of the yellow (4 ()) lion, the turning piece will be in the position again, and the two base rods (32) will also press the two round beads at the same time. Extend the socket hole_inner wall surface and into the ring groove (223) of the rod (11). Conversely, if you want to replace the non-moving parts (_ move to the-position, and pay attention to your quick release connector for Guangzhuang Power Tools, you can easily operate the main purpose of quickly removing the tools used by power tools 20 M261341 At the same time, it does not require auxiliary tools, so it is more convenient. It is particularly noted that the drive unit of the power tool has a hexagonal socket for the rod of the quick connector to engage, and the tool shank and the The socket hole of the joint is also a polygonal concave-convex combination structure, so it can reliably transmit the power of the drive unit, without the problem of idling of the tool caused by the improper locking.
