The insertion abutment portion 121 and the extraction abutment portion 122 are provided facing each other. When the user rotates the housing 110 in different directions, the input abutment portion and the extraction abutment portion 122 abut against corresponding abutment portions on the second object 300 respectively, so as to form an active force for inserting the first object 200 into or pulling out the second object 300 by leverage. It should be understood that the insertion abutment 121 and the extraction abutment 122 are not necessary. The extraction aid function of the extraction aid can be realized by other structures.

Several assembling holes 124 are also opened on the first housing part 120, which are used for The second housing part 130 is assembled. It should be understood that the assembling hole 124 is not necessary, and the first casing part 120 and the second casing part 130 can be bonded or directly formed into one body.

A specific structure of the second case member 130 will now be described with reference to FIGS. 5A and 5B . The second housing part 130 includes a plate-shaped side wall and an end wall 131 vertically extending from the side wall. The side wall of the second housing part 130 is provided with a first pivot hole 123', a first locking groove 125', a second locking groove 126', and a locking groove spacer 127'. The positions of these features correspond to the positions of the corresponding features on the first housing part 120 respectively. It should be understood that the positions of the first locking groove 125, the second locking groove 126, the locking groove spacer 127 of the first housing part 120 and the first locking groove 125', the second locking groove 126' and the locking groove spacing part 127' of the second housing part 130 respectively correspond to the positions of the locking blocks 144 on the two side surfaces of the handle 140, and each locking groove on the first housing part 120 does not necessarily correspond to each locking groove on the second housing part 130 . Moreover, when the number and position of the locking blocks 144 change, the positions and quantities of the first locking groove 125, the second locking groove 126, the locking groove spacer 127, the first locking groove 125', the second locking groove 126', and the locking groove spacer 127' can be changed accordingly.

The end wall 131 extends along most of the length of the edge of the side wall of the second housing part 130 . The end wall 131 has a certain thickness. In this way, on the side of the end wall 131 facing the inside of the housing 110 , a first handle accommodating portion 132 and a second handle accommodating portion 133 are formed by recesses in the thickness direction of the end wall 131 . The first handle accommodating portion 132 and the second handle accommodating portion 133 respectively correspond to the shape of the free end of the handle 140 so as to receive the pivoting end of the handle 140 therein. The first handle accommodating portion 132 and the second handle accommodating portion 133 are spaced apart by a certain interval along the pivoting direction of the handle 140 , and the interval may be approximately 90 degrees or may be changed according to the pivoting range of the handle 140 . The spacing may be in the range of approximately 45 degrees to 180 degrees, such as 45 degrees, 60 degrees, 120 degrees, 150 degrees, 180 degrees, etc.

Therefore, the extraction aid 100 of the present application is mounted on the first object 200 and can abut against the second object 300 . When the user wants to insert or pull out the first object 200, the housing 110 of the extraction aid 100 can be rotated, and the insertion abutting portion 121 or the extraction abutting portion 122 on the housing 110 abuts against the second object 300, and the first object 200 can be easily inserted or pulled out by leverage.

As for the handle 140 of the extraction aid 100 of the present application, on the one hand, it can be locked to the housing 110, thereby driving the rotation of the housing 110 by operating the handle 140 ( FIG. 9B ); For example, the guiding portion can guide unrelated objects such as the cable 400 to avoid the surface of the first object 200 so as to facilitate the user to operate the first object 200 .

In one embodiment, the folded position and the unfolded position of the handle 140 have an angular difference of approximately 90 degrees, and the pivot axis of the handle 140 is approximately parallel to the pivot axis of the housing 110 . In this way, the handle 140 can be rotated to a position conforming to the surface of the first object 200 , or rotated to a position perpendicular to the surface of the first object 200 . In other embodiments, the angle difference between the folded position and the unfolded position of the handle 140 can be other values, and the angle difference can be in the range of approximately 45 degrees to 180 degrees, such as 45 degrees, 60 degrees, 120 degrees, 150 degrees, 180 degrees, etc.

To sum up, the present application provides a puller 100 , which can not only assist the user to insert the first object 200 into or pull out the second object 300 , but also provide a guide on the surface of the first object 200 . Moreover, due to the special design of the motion limiting mechanism between the handle 140 and the housing 110 of the present application, the user only needs to operate the handle 140 with one hand to complete all the above functions. function, thus providing users with a simple and fast experience.
