DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] As shown in Figures 1-6 : a novel twist switch, comprising a main body 1 internally provided with a switching piece 4, a shaft sleeve 2 at the top of the main body 1 is rotatably installed with a handle 3 through a riveting piece 201, the handle 3 has one end penetrating into the internal cavity of the main body 1 and abutting with the switching piece 4, when the handle 3 is pushed to make the switching piece 4 be pushed, one end of the switching piece 4 can contact with the contact terminal 6 on the side of the main body 1 and realize circuit connection.

[0024] Further, the main body 1 comprises two parts of the upper shell 101 and the base 102 assembled with each other, wherein the base 102 is provided with a support table 5 for mounting the switching sheet 4, as shown in Figure 2 , Figure 6 The support table 5 is similar to a U-shaped structure and is inserted with the common terminal 8 at the middle part, so as to be fixed to the top surface of the base 102. The support table 5 has corresponding open grooves 501 at the front and back sides, and the switching sheet 4 with the V-shaped design is placed at the open grooves 501 of the support table 5, specifically supported by the top supporting convex edges 511 formed upward by the open grooves 501. Due to the arrangement of the open grooves 501, the support table 5 is also formed with stop portions 502. In order to prevent the switching sheet 4 from sliding forward and backward, the protruding portions 401 are formed at the left and right sides of the switching sheet 4. When the switching sheet 4 is placed on the support table 5, the protruding portions 401 are located between the stop portions 502 at the front and back of the support table 5. In this way, the switching sheet 4 can only be flipped and cannot be slid by the push handle 3, which improves the use stability of the overall structure to a certain extent.

[0025] Specifically, the switching sheet 4 is also formed with the folded edges 402 at the two ends, so that the switching sheet 4 can have a larger contact surface with the contact terminal 6.

[0026] Further, the upper shell 101 and the base 102 are also formed with a plurality of buckling grooves 111 and buckling blocks 112, which are assembled in a buckling manner to form the main body 1. In the existing design, the upper shell 101 and the base 102 are generally assembled in a riveting relationship. Specifically, the upper shell 101 is formed with four rivet feet at the bottom thereof, and the base 102 assembled with the internal components is assembled into the upper shell 101. The rivet feet of the upper shell 101 are manually bent by a jig to lift the base and the internal components. However, in actual operation, there may be certain errors in manually bending the rivet feet, which may cause gaps. Therefore, this assembly method does not really fix the upper shell 101 and the base 102 to form a whole. In some special assembly processes, the gaps may cause the upper shell 101 and the base 102 to shake with each other, which may cause the internal components to shift. The present design uses a plurality of buckling structures to assemble the upper shell 101 and the base 102 with each other, which maximally avoids the above-mentioned component shifting problem and improves the structural stability of the main body 1.

[0027] Further, the push handle 3 used for pushing the one end of the switching piece 4 is further formed with a plug hole, a top head 7 is elastically inserted into the plug hole through a spring, since the top head 7 can be elastically extended and retracted, no matter where the push handle 3 is pushed, the top head 7 can continuously abut against the switching piece 4, in addition, in order to avoid that the top head 7 scratches the switching piece 4, the end of the top head 7 can be designed as an arc surface; since the switching piece 4 is designed as a V-shaped structure during use, the operator only needs to push the push handle 3 for a certain distance, makes the switching piece 4 overturn for a certain angle, the switching piece 4 can automatically complete the subsequent overturning action, and then the gear switching is realized.

[0028] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the utility model.
