The invention relates to the technical field related to fitness aids, in particular to a gripper structure.

According to the common gripping device in the market, as disclosed in the previous case of Chinese Patent No. M330845, it can only provide users with palm grip strength training, and cannot be used for other purposes. For this reason, users need to deal with different training items separately Purchasing training equipment for special projects is very wasteful and takes up space.

The structure of the previous proposal No. M330845 is to adjust the tension of the tension spring by adjusting the screw of the screw. However, the adjustment screw does not have an additional fixed structure, which is easy to spin due to external force or vibration, thereby changing the tension of the tension spring. , Causing the user to adjust to the required tension before use, which is very inconvenient and troublesome.

In addition, pressing the crutches acts like a human's third foot (or even the fourth foot), and is used to assist the user in standing and walking. The weight of the body is transferred to the crutches through the hands, thereby reducing the weight and pressure exerted on the legs, and increasing the fulcrum to maintain the balance of the body on uneven roads.

The common crutches in the market mainly consist of a straight and rigid body and a crutches connected to the body for the user to hold. One end of the body abuts against the ground, and the body weight is supported on the crutches to spread Put pressure on the legs and knees.

However, when the user holds the crutches on the ground, although the weight of the body is applied to the crutches, the opposite crutches will also transmit the ground reaction force (force) back to the user's hand, causing the user's hand Discomfort, the user's hands will feel sore for a long time.

In addition, there are trekking poles that are similar to crutches, which provide climbers and hikers who can easily complete their trips. The way of use is to hold the handle of the trekking pole in a grip, like a state of clenching a fist for a long time, which will make the user feel very uncomfortable and increase the fatigue of the user when climbing.

In view of the above-mentioned problems and deficiencies of the prior art, one purpose of the present invention is to provide a gripper structure, which can provide users with rapid adjustment of tension through the innovative design of the structure.

Another object of the present invention is to provide a gripper structure, which can be combined with the rod body through the innovative design of the structure to reduce the anti-shock force experienced when the rod body is used.

According to the above objective of the present invention, a structure of a gripper is proposed, which includes a first grip, a second grip pivotally connected to the first grip, an adjustment seat movably accommodated in the second grip, and The tension spring pivotally connected between the first handle and the adjusting seat, a set of positioning ring set at one end of the second handle, an adjusting rod that penetrates the fixed position and screwed on the adjusting seat, and a set of support attached to the outer periphery of the adjusting rod The lock base and an eccentric wrench pivotally connected with the adjusting rod. With the composition of the above structure, the user can quickly adjust the tension of the tension spring and also provide the clamping of the mobile device.

Therefore, the foregoing is an introduction to the components and assembly methods of a preferred embodiment of the gripper structure provided by the present invention. Hereinafter, the features of the embodiments of the present invention are introduced as follows.

First, the user can hold the straight handle portion 12 and the crank portion 21 of the first and second handles 10 and 20, and apply force to train the user to grasp the hand. When the grip strength does not meet the user's needs, it can be changed by adjusting the tension of the tension spring 32.

Please refer to Figure 7, when you want to adjust the tension of the tension spring 32, first rotate the compression wheel 37 away from the transverse groove 22 to form a retreat space for the support lock seat 36 and the grip adjustment wheel 35. It can move away from the transverse groove 22, and the two end surfaces of the tooth part 353 of the grip force adjusting wheel 35 no longer fit with the ring tooth flower 3624 of the support lock seat 36 and the positioning tooth flower 336 of the positioning ring 33.

At this time, the torsion grip adjusting wheel 35 synchronously links the adjusting screw 34 to rotate, so that the adjusting seat 31 screwed on the outer peripheral side of the adjusting screw 34 moves axially along the adjusting screw 34 to change the tension of the tension spring 32 connected to the adjusting seat 31.

Please refer to Figures 8-9. Due to different body shapes, men and women, ages, etc., their palm openings are also different. To meet the needs of different users' palm openings, the first and second grips 10, 20 can be tightly pressed. Make the opening of the straight handle portion 12 and the crank portion 21 at the minimum (or preset opening degree), and then move the straddle 38 to adjust the position of the straddle 38 to sink in the different elevation grooves 254 of the elevation portion 25 to form different elevation angle tops The matching positioning groove 15 is used to adjust the opening degree of the straight handle portion 12 and the crank portion 21 of the first and second handles 10 and 20.

In addition to holding the first and second grips 10 and 20 for grip strength training, the When the grip tube hole 422 on the lower end of the third grip 40 is sleeved on the outer circumference of a fixed post (not shown in the figure), the user can further cooperate with the arm to exert downward pressure to further achieve arm muscle strength training .

Please refer to Figures 2 and 10, when the third handle 40 is sleeved on the outer circumference of a fixed post, the angles of the first and second handles 10, 20 can also be adapted to the user’s body shape to match the quick release assembly 50 for adjustment.

The adjustment method is to pull the quick-release wrench 54 in conjunction with the quick-release screw 53 to screw the quick-release nut 51, so that the extension pivot part 27 of the second handle 20 is no longer tightly clamped, so that the second handle 20 can be fast The detaching screw 53 is the axis, and the angle can be adjusted relative to the third handle 40 to adapt to different users' body shapes or holding methods.

After the second handle 20 is adjusted to the preset position, the reverse quick-release wrench 54 pushes the eccentric pivot part 542 against the second handle 20 again, and links the quick-release nut 51 at one end of the quick-release screw 53 together. The extension pivot part 27 is clamped to position the angle between the first and second handles 10 and 20 relative to the third handle 40.

Please refer to Figures 11 and 12, insert the third handle 40 at one end of the crutches unit 80, and when used as a crutch or trekking pole, the user can hold it in the first and second grips with a half-open grip. The handles 10 and 20 link the turning unit 80 to move and abut the grounding surface (not shown in the figure), and when the turning unit 80 touches the grounding surface, the reaction force will be offset by the tension spring 32; in this way, the user During walking, the palm of the hand exhibits a repetitive motion of one grip and one grip, which is different from the state of clenching fists and fingers for a long time in the previous technique, thereby reducing the counter-shock force transmitted to the user's hand and allowing the user Tight and loose palms stimulate blood circulation at the end and effectively relieve physical fatigue.

In addition to reducing the pressure on the user's palm by holding the first and second grips 10 and 20 as described above, the wristband 70 can be fitted to the user's palm to further reduce the grip of the user's palm on the wrist. Spread the palm of your hand Body weight allows users to walk more easily.

Please refer to Figures 11, 13 to 14, the support lock base 36 further optionally provides a support clamp 60 for locking, which is convenient for holding mobile devices (such as mobile phones). Together with the turning unit 80, a self-timer can be formed .

When the mobile device is clamped by the clamp 61 of the support clamp 60 and the angle is to be adjusted, the clamp screw 63 (clamp nut 62) can be loosened to expand the clamp pivot groove 614 and allow the support clamp 60 to adjust. It is also possible to further retreat the compression wheel 37 away from the transverse groove 22 to form a retreat space for the support lock base 36 to move away from the transverse groove 22 and allow the ring portion of the support lock base 36 to be toothed 3624. It no longer fits with the flower tooth portion 353 of the grip adjusting wheel 35. At this time, the twisting support lock seat 36 adjusts the direction. After the position is reached, it can be locked by the above reverse operation.

In this way, the user can hold the crutch unit 80 to take a selfie, or hold the moving device to take a photo.

Please refer to Figures 15 to 19, which is an embodiment of the second tension adjustment mechanism to replace the first tension adjustment mechanism, which includes: an adjustment seat 31, a tension spring 32, a positioning ring 33, and an adjustment rod 34 ', a support lock seat 36', a straddle 38, and an eccentric wrench 39; wherein the structure of the adjusting seat 31, the tension spring 32, the positioning ring 33 and the straddle 38 is the same as the above example, so we will not repeat it. The only difference is:

The adjusting rod 34' has a rod pivot hole 345, a threaded section 343, and an annular groove 344 formed in sequence along the outer peripheral side of the adjusting rod 34' extending direction. And the adjusting rod 34' has one end extending through the ring shaft hole 332 of the positioning ring 33, and screwing through the adjusting seat screw hole 312 of the extending adjusting seat 31, and is received in the movable groove 222 of the transverse groove portion 22, and the ring groove 344 The two pins P1 penetrated through the two pin holes 26 of the second handle 10 are clamped and limited.
