DETAILED DESCRIPTION

[0029] The technical solution of the embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, a guide ruler mechanism for a stripping pliers according to an embodiment of the present invention comprises a base 201, a guide ruler 202 and a control member 203. The guide ruler 202 and the control member 203 are located on the base 201. The guide ruler 202 and the control member 203 are adapted.

[0031] In the above embodiment, the position of the guide ruler 202 is adjusted by setting the control member 203. Compared with the prior art, this embodiment improves the convenience of using the guide ruler 202. The control member 203 is used to adjust the movement of the guide ruler 202. Preferably, the position of the guide ruler 202 is adjusted by pressing the control member 203. Of course, other methods can also be used to adjust the control member 203.

[0032] Preferably, the base 201 is provided with a through hole and a concave hole that are interconnected, one end of the guide ruler 202 passes through the through hole of the base 201, and one end of the control member 203 is located in the concave hole of the base 201. The base 201 is provided with a through hole and a concave hole that are interconnected, the guide ruler 202 passes through the through hole, and one end of the control member 203 is located in the concave hole of the base 201, and the control member 203 and the guide ruler 202 can contact, thereby realizing the position adjustment of the guide ruler 202 by the control member 203. The concave hole may not pass through the base 201, or may pass through the base 201. When the concave hole passes through the base 201, it is easy to install.

[0033] Preferably, the control member 203 includes a control body 2032 and a first elastic body 2033, and the concave hole of the base 201 is provided with a limiter. The first end of the control body 2032 is located in the concave hole. One end of the first elastic body 2033 is against the limiter, and the other end of the first elastic body 2033 is adapted to the second end of the control body 2032. The control body 2032 is provided with an adjustment part 20321. The adjustment part 20321 is adapted to the guide ruler 202 to achieve the adjustable position of the guide ruler 202. Preferably, the lower part of the adjustment part 20321 is adapted to the guide ruler 202. More preferably, the control member 203 also includes a base 2031, and the base 2031 is located outside the concave hole. The second end of the control body 2032 is fixedly connected to the base 2031. The other end of the first elastic body 2033 and the second end of the control body 2032 are adapted to: the other end of the first elastic body 2033 is against the base 2031.

[0034] In the above embodiments, the structure of the limiter can be various, for example, a boss is provided in the concave hole of the base 201 as a limiter. Preferably, the boss is an annular boss. For another example, a limit step is provided in the concave hole of the base 201 as a limiter. That is to say, the concave hole of the base 201 includes an upper hole and a lower hole, the aperture of the upper hole is larger than the aperture of the lower hole, and a limit step is formed between the upper hole and the lower hole. The lower hole and the control body 2032 are clearance-matched and adapted. In this preferred example, the lower hole can also serve to limit the control body 2032 to prevent it from shaking in the horizontal direction during operation. The lower hole and the control body 2032 are clearance-matched and adapted. The control body 2032 moves along the lower hole.

[0035] In the above preferred embodiment, when working, the base 2031 is pressed, and the base 2031 moves downward until it contacts the base 201 and stops moving. When the base 2031 moves downward, the first elastic body 2033 is compressed. Because the control body 2032 is fixedly connected to the base 2031, when the base 2031 moves downward, the control body 2032 also moves downward. When the control body 2032 moves downward, the guide ruler 202 does not move in the longitudinal direction, but the lower part of the adjustment part 20321 of the control body 2032 gradually separates from the guide ruler 202, and the force of the adjustment part 20321 of the control body 2032 on the guide ruler 202 is reduced, so that the guide ruler 202 can move in the horizontal direction.

[0036] When the base 2031 is not pressed, the lower part of the adjusting portion 20321 fits with the guide ruler 202. Due to the action of the first elastic body 2033, the control body 2032 has a tendency to move upward. In this way, the lower part of the adjusting portion 20321 of the control body 2032 contacts and fits with the guide ruler 202, exerting a longitudinal force on the guide ruler 202, so that it cannot easily move in the horizontal direction.

[0037] In this preferred embodiment, the position of the guide ruler 202 is easily adjusted by pressing the base 2031. This action process is simple and easy to control. In addition, even if the base 2031 is not pressed, the position of the guide ruler 202 can be adjusted by directly moving the guide ruler 202. At this time, the force of moving the guide ruler 202 is greater than the friction force generated by the control body 2032 on the guide ruler 202.

[0038] The control body 2032 is provided with an adjusting part 20321. The adjusting part 20321 is used to adjust the position of the guide ruler 202. The adjusting part 20321 can have various structures, and the following two structures are selected in this preferred example.

[0039] The first structure: Figure 3 As shown, the adjusting portion 20321 is a through hole. The guide ruler 202 passes through the through hole of the control body 2032, the lower part of the through hole is adapted to the lower part of the guide ruler 202, and the middle part of the through hole is larger than the guide ruler 202. The longitudinal cross-section of the through hole can be elliptical. The guide ruler 202 passes through the through hole. The middle part of the through hole is larger than the guide ruler 202, and the middle width of the through hole can be larger than the diameter of the guide ruler 202. In this way, when the control body 2032 moves downward and the middle part of the through hole moves to the guide ruler 202, the force exerted by the control body 2032 on the guide ruler 202 is greatly reduced, or even zero, so that the guide ruler 202 is easily moved by external force and changes its position.

[0040] In this preferred example, the central axis of the control body 2032 intersects with the central axis of the guide ruler 202 .

[0041] The second structure: Figure 4 As shown, the adjusting portion 20321 is concave, the lower portion of the adjusting portion 20321 is adapted to the lower portion of the guide ruler 202, and the central axis of the control body 2032 does not intersect with the central axis of the guide ruler 202. The central axis of the control body 2032 does not intersect with the central axis of the guide ruler 202, which makes it easy to set the positions of the control body 2032 and the guide ruler 202 and facilitate installation.

[0042] In this preferred embodiment, the adjusting portion 20321 is concave. When the control body 2032 moves downward, the middle of the adjusting portion 20321 moves to the guide ruler 202, and the force exerted by the control body 2032 on the guide ruler 202 is greatly reduced, or even zero, so that the guide ruler 202 is easily moved by external force and changes its position.

[0043] Preferably, assuming that the maximum movable distance from the base 2031 to the base 201 is a, the diameter of the guide ruler 202 is d, the height of the through hole or the height of the curved surface is h, the stripping pliers satisfies formula (1):

[0044] a+d<h Formula (1).

[0045] Formula (1) ensures that the guide ruler 202 will not contact the top surface of the adjusting portion 20321 during the movement of the base 2031. In this way, even when the base 2031 moves downward to the limit position, the force exerted by the control body 2032 on the guide ruler 202 is smaller than the force exerted by the control body 2032 on the guide ruler 202 when the base 2031 is not pressed. This makes the guide ruler 202 easy to move.

[0046] Preferably, the guide ruler 202 includes a body 2021 and a guide rod 2022 connected to the body 2021, and the guide rod 2022 penetrates the base 201. The guide rod 2022 moves in the through hole of the base 201 to change the position of the body 2021.

[0047] Preferably, the guide ruler mechanism 2 further comprises a second elastic body 3, which is sleeved on the guide rod 2022, and one end of the second elastic body 3 abuts against the base 201, and the other end abuts against the body 2021. When the base 2031 is pressed, the force of the control body 2032 on the guide ruler 202 gradually decreases. When the force of the control body 2032 on the guide ruler 202 is less than the elastic force generated by the second elastic body 3, the guide ruler 202 automatically moves under the action of the second elastic body 3. This does not require manual manipulation of the body 2021. Of course, manual manipulation of the body 2021 can still achieve position adjustment of the guide ruler 202.

[0048] Preferably, a groove is provided on the side of the body 2021 facing the base 201, one end of the guide rod 2022 is connected to the groove wall of the groove, and the guide rod 2022 and the groove form an annular gap, and one side of the second elastic body 3 is located in the annular gap. When the second elastic body 3 is compressed, the second elastic body 3 can be located in the annular gap in whole or in part. The annular gap is provided. On the one hand, when the second elastic body 3 is compressed, the annular gap becomes a accommodating space for the second elastic body 3, and the wall surface of the body 2021 can directly contact the base 201; on the other hand, the structure is more compact and space-saving.

[0049] In order to prevent the guide rod 2022 from completely passing through the through hole of the base 201, causing the guide rod 2022 to be separated from the through hole, a fixing piece is provided at one end of the guide rod 2022 passing through the base 201. The size of the fixing piece is larger than the size of the through hole. During the movement of the fixing piece, it will not enter the through hole.

[0050] Preferably, a stopper 20211 is provided on the body 2021, and a peeling space is formed between the stopper 20211 and the clamp body 1. When the guide ruler 202 is manually moved, the finger is located in the peeling space, and the position of the body 2021 is easily changed by applying force to the stopper 20211.

[0051] like Figure 1As shown, when stripping, a cable 4, such as an electric wire or a conductor, is placed in the stripping pliers from left to right. When one end of the cable 4 reaches the positioning end face of the guide ruler 202 of the guide ruler mechanism 2, the cable 4 is blocked from extending further to the right. At this time, the stripping length is the distance between the blade of the stripping pliers for removing the insulation layer of the cable 4 and the positioning end face of the guide ruler 202, so adjusting the distance between them can adjust the stripping length.

[0052] The guide ruler mechanism 2 of the above embodiment can achieve precise control and can be controlled by one hand. Figure 1 As shown, in normal state, the guide rod 2022 has a tendency to move rightward under the action of the second elastic body 3. The control body 2032 has a tendency to move upward under the action of the first elastic body 2033.

[0053] Preferably, the elastic force of the first elastic body 2033 is greater than the elastic force of the second elastic body 3, so that the arc surface of the lower part of the adjusting portion 20321 of the control body 2032 is in contact with the guide rod 2022 under the action of the first elastic body 2033. Since the elastic force of the first elastic body 2033 is greater than the elastic force of the second elastic body 3, the guide rod 2022 cannot continue to pop outward under the action of the second elastic body 3, and the guide rod 2022 is locked in position.

[0054] When the position of the guide rod 2022 needs to be adjusted, the base 2031 of the control member 203 is pressed with a finger, so that the arc surface of the lower part of the adjusting portion 20321 of the control member 2032 is separated from the contact with the guide rod 2022, and the guide rod 2022 is ejected to the right under the action of the second elastic body 3, and the maximum ejection position is when the fixing part of the guide rod 2022 contacts the base 201. Stop pressing the control member 203 to lock (position) the position of the guide rod 2022.

[0055] Of course, in this embodiment, the guide rod 2022 can also be pushed and pulled to move left and right to adjust the position of the guide rod 2022 without pressing the control member 203 .

[0056] When the length to be stripped exceeds the maximum extension length of the guide ruler, the guide ruler 202 hinders the stripping process. At this time, the body 2021 of the guide ruler 202 can be rotated along the axis of the guide rod 2022 to separate the body 2021 from the stripping area, so that the cable 4 can extend to the right without affecting the stripping.

[0057] The present invention further provides a wire stripping pliers, comprising a base 1 and the guide ruler mechanism 2 of the above embodiment. The base 201 in the guide ruler mechanism 2 is fixedly connected to the base 1.

[0058] In the stripping pliers of the embodiment of the present invention, one end of the guide ruler 202 passes through the through hole of the base 201, and one end of the control member 203 is located in the concave hole of the base 201. The control member 203 is in contact with the guide ruler 202. During operation, the position of the guide ruler 202 is adjusted by the control member 203. The guide ruler 202 moves in the through hole of the base 201, thereby changing the position of the guide ruler 202.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above specific embodiments. The above specific embodiments and the description in the specification are only for further illustrating the principles of the present invention.
