[0005] Preferably, the end of the inner push rod is provided with a groove that cooperates with the end of the sub-buckle.
[0006] Preferably, a handle is fixed to one end of the inner push rod away from the groove.
[0007] Preferably, the return spring sleeve is arranged on the outside of the inner push rod, and two ends of the return spring sleeve are fixedly connected to the handle and the outer sleeve respectively.
[0008] Preferably, a protective tube is fixed to the middle of the side wall of the handle, and the protective tube is sleeved on the outside of the reset spring.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0017] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0018] See also Figures 1 to 4 The utility model provides a handheld tool that is easy to assemble, comprising an outer sleeve 1 and an inner push rod 2 slidably connected to the inner side of the outer sleeve 1, the outer sleeve 1 and the inner push rod 2 are connected by a reset spring 3, one end of the outer sleeve 1 is symmetrically provided with a clamping device 4 for clamping a sub-clip, the clamping device 4 includes a clamping plate 5 that slides radially along the outer sleeve 1, one end of the clamping plate 5 is in an arc shape, and guide portions 6 are provided on both sides of the arc-shaped end of the clamping plate 5, a U-shaped frame 7 is fixed to the outer wall of the outer sleeve 1, and the other end of the clamping plate 5 is connected to the U-shaped frame 7 by a telescopic spring 12.
[0019] The end of the inner push rod 2 is provided with a groove 8 that matches the end of the sub-buckle, so that the sub-buckle remains parallel to the outer sleeve 1.
[0020] A handle 9 is fixed to one end of the inner push rod 2 away from the groove 8 to facilitate the application of force.
[0021] The return spring 3 is sleeved on the outside of the inner push rod 2, and the two ends of the return spring 3 are fixedly connected to the handle 9 and the outer sleeve 1 respectively, so the return spring 3 is relatively stable.
[0022] A protective tube 10 is fixed to the middle of the side wall of the handle 9 , and the protective tube 10 is sleeved on the outside of the reset spring 3 , so as to facilitate the hand to hold the handle 9 and prevent the reset spring 3 from pinching the hand.
[0023] The handle 9 is provided with anti-skid patterns 11 on its outer side to prevent slipping.
[0024] It should be emphasized that the spring coefficient of the telescopic spring 12 is relatively small, and some sub-buckles are already inserted into the mother buckle when leaving the factory, and do not need to be positioned. The clamping device 4 can be removed, which can also meet the use requirements.
[0025] Working principle: first install the mother buckle into the installation station, then insert the end of the sub-buckle into the outer sleeve 1, the end of the sub-buckle contacts the inner wall of the outer sleeve 1, when the end of the sub-buckle contacts the guide part 6, the end squeezes the clamping plate 5, so that the clamping plate 5 slides to the outside of the outer sleeve 1, and the telescopic spring 12 is compressed. When the end of the sub-buckle passes through the clamping plate 5, the clamping plate 5 slides to the inside of the outer sleeve 1 under the restoring force of the telescopic spring 12, and the clamping plate 5 clamps the thread of the sub-buckle. When the end of the sub-buckle contacts the groove 8, stop pressing the sub-buckle. Due to the existence of the clamping plate 5, the sub-buckle and the outer sleeve 1 remain parallel.
[0026] Next, insert the threaded part of the sub-buckle into the female buckle, and press the handle 9, which squeezes the inner push rod 2 to make the sub-buckle slide along the outer sleeve 1. When the end of the sub-buckle contacts the guide part 6, the end and the inner push rod 2 squeeze the clamping plate 5 in turn, making the clamping plate 5 slide to the outside of the outer sleeve 1. When the sub-buckle is fully inserted into the female buckle, the inner push rod 2 is just located at the end of the outer sleeve 1. Release the handle 9 and reset it under the action of the reset spring 3. The force of the reset spring 3 is relatively large compared to the force of the telescopic spring 12, and the telescopic spring 12 will also reset when it is separated from the action of the inner push rod 2.
[0027] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
