Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1-7 shown, a folding grip pressing device includes a housing 1-1 and a grip 2-1 connected to the housing 1-1. Fixing mechanisms are provided on both sides inside the housing 1-1. The grip 2-1 is respectively arranged on the fixing mechanisms. The inside of the grip 2-1 has a cavity 2-5 of the grip. A pulling mechanism is arranged in the cavity 2-5 of the grip. One end of the pulling mechanism is fixed to one end of the grip 2-1, and the other end is sleeved on the fixing mechanism. The grip 2-1 can extend, retract and rotate along the fixing mechanism through the pulling mechanism.

[0025] Specifically, the fixing mechanism includes fixing screws 5. The fixing screws 5 penetrate through the housing 1-1 and are fixed to the housing 1-1. A set of bolt holes 1-2 and nut holes 1-3 are respectively opened on both sides of the housing 1-1. The two fixing screws 5 respectively penetrate through the two sets of bolt holes 1-2 and nut holes 1-3 and are fixed to the housing 1-1 through nuts 6. The grip 2-1 is arranged on both sides of the housing 1-1. An anti-slip sleeve 7 is arranged outside the grip 2-1. One end of each of the two grips 2-1 is respectively inserted into the housing 1-1 and is rotatably connected to the two fixing screws 5. A waist hole 2-2 of the grip is opened at one end of the grip 2-1 inserted into the housing 1-1. The fixing screw 5 penetrates through the waist hole 2-2 of the grip. The grip 2-1 can slide or rotate along the fixing screw 5 through the waist hole 2-2 of the grip.

[0026] Specifically, the pulling mechanism includes a tension spring 3-1 and a fixing pin 4. The inside of the grip rod 2-1 has a grip rod cavity 2-5. One end of the grip rod cavity 2-5 away from the housing 1-1 is provided with a grip rod pin slot 2-3. The fixing pin 4 is fixed in the grip rod pin slot 2-3. The tension spring 3-1 is arranged in the grip rod cavity 2-5. Both ends of the tension spring 3-1 have a first tension spring hole 3-2 and a second tension spring hole 3-3 respectively. The first tension spring hole 3-2 is sleeved outside the fixing screw 5, and the second tension spring hole 3-3 is sleeved outside the fixing pin 4.

[0027] In the initial folded state, the grip rod end faces 2-4 of the two grip rods 2-1 are abutted against the upper end face 1-4 of the housing. At both ends inside the housing 1-1, there are housing steps 1-7 that can limit the rotation of the two grip rods 2-1. The housing steps 1-7 are located beside the grip rods 2-1. At this time, the grip rods 2-1 cannot rotate.

[0028] In the use and unfolded state, the two grip rods 2-1 can be inserted into the side end face 1-6 of the housing. At this time, the two grip rods 2-1 are on the same axis and cannot rotate.

[0029] A housing arc surface 1-5 is arranged between the side end face 1-6 of the housing and the housing step 1-7 to facilitate the guiding when the grip rod 2-1 rotates.

[0030] When the utility model is installed, the operator puts the tension spring 3-1 into the grip rod cavity 2-5, aligns the first tension spring hole 3-2 to the grip rod waist hole 2-2, then places the grip rod 2-1 into the cavity of the housing 1-1, aligns the grip rod waist hole 2-2 to the bolt hole 1-2, then inserts the fixing screw 5 into the bolt hole 1-2 to the nut hole 1-3, then places the nut 6 into the nut hole 1-3 and tightens it. The fixing screw 5 passes through the grip rod waist hole 2-2 and the first tension spring hole 3-2. Next, use a tool to pull the second tension spring hole 3-3 to the grip rod pin slot 2-3. At this time, insert the fixing pin 4 into the second tension spring hole 3-3. The fixing pin 4 passes through the second tension spring hole 3-3. Loosen the tool to make the fixing pin 4 fall into the grip rod pin slot 2-3 to complete the installation of one side as a whole. Because the two grip rods 2-1 on both sides are symmetric, use the same method to complete the installation of the grip rod 2-1 on the other side, and the overall installation is completed.

[0031] When the operator needs to unfold the grip 2-1, in the folded state, pull out the grip 2-1. The reason for pulling out is the block of the housing step 1-7. At this time, the end face 2-4 of the grip cannot rotate due to the block of the housing step 1-7, thus forming a locking effect. Assuming the directions in the figure are up, down, left, and right, pull the grip 2-1 downward to make the grip 2-1 leave the upper end face 1-4 of the housing, and rotate the grip 2-1 so that the end face 2-4 of the grip contacts along the arc surface 1-5 of the housing. Further rotate it by ninety degrees to align the end face 2-4 of the grip with the left and right ends of the housing 1-1. At this time, due to the acting force of the tension spring 3-1, quickly fit the end face 2-4 of the grip with the side end face 1-6 of the housing and complete the fixation. The unfolding of the other grip 2-1 is completed in the same way. In the unfolded state, which is the working state, hold the grips 2-1 with both hands to complete the required actions;

[0032] When the operator needs to fold the grip 2-1, pull out the grip 2-1 in the outward direction to make the end face 2-4 of the grip leave the side end face 1-6 of the housing. At this time, the locking is released and the grip 2-1 can rotate. The end face 2-4 of the grip rotates along the arc surface 1-5 of the housing to the upper end face 1-4 of the housing to complete the fitting. Due to the blocking effect of the housing step 1-7, the end face 2-4 of the grip cannot move, thus forming a locking effect. The other grip 2-1 is also folded in the same way.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
