Description

Technical field:

[0001] The utility model relates to the technical field of fishing gear products, in particular to a folding handle screw and a universal corner turret. Background technology:

[0002] Fishing is the abbreviation of fishing with a fishing rod, commonly known as "fishing", which refers to an activity of using fishing rods, fish hooks, fishing lines and other fishing gear to pull fish out from rivers, lakes, seas and reservoirs.

[0003] Fishermen usually hold a fishing rod when fishing. The longer the fishing rod, the worse the stability. The longer the fishing time, the greater the shaking, which can easily make the fisherman feel tired, greatly affecting the fishing effect. For this reason, people have successfully developed a fishing rod turret bracket on a fishing chair or a fishing box. People can place the fishing rod on the fishing rod turret bracket during fishing, without having to hold the fishing rod all the time, making fishing more casual and relaxing.

[0004] The Chinese utility model patent with the announcement number CN219781310U discloses a universal turret for fishing rods, which includes a base, a sliding mechanism, a swing arm and a gun barrel, wherein the sliding mechanism is slidably arranged on the base, the gun barrel is movably connected to one end of the swing arm, and the swing arm is rotatably connected to the sliding mechanism. The fishing rod is inserted into the gun barrel of the utility model and then locked, the gun barrel can be adjusted in front and back angles on the swing arm, the swing arm can be adjusted in the left and right directions of the sliding mechanism, and the sliding mechanism can slide in the front and back directions of the base, such mutual cooperation can realize the multi-directional adjustment of the universal turret for fishing rods of the utility model, which is more practical and more applicable.

[0033] The utility model is further described below in conjunction with specific embodiments and drawings.

[0034] See Figure 1-4 Shown is a folding handle screw, which can be applied to the barrel of a turret to lock a fishing rod passing through the barrel.

[0035] The folding handle screw 1 includes a screw rod 11 and a screw head 12 fixed to the end of the screw rod 11, which is a conventional structure. The utility model makes the following improvements to the folding handle screw 1, specifically: the screw head 12 is provided with a storage groove 121, and a rotatable handle 13 is provided in the storage groove 121. The handle 13 can be folded and stored in the storage groove 121, and the handle 13 can also be opened outward relative to the storage groove 121 to protrude from the outside of the screw head 12 to increase the size of the screw head 12. When the folding handle screw 1 needs to be turned, the handle 13 is opened outward relative to the storage groove 121, so that the handle 13 protrudes from the outside of the screw head 12 to increase the size of the screw head 12, so that it is convenient to pinch the handle 13 and / or the screw head 12 with the hand, and then it is more convenient to pinch the handle 13 and / or the screw head 12, so as to drive the handle 13 and / or the screw head 12 to rotate with force, which is more convenient to operate and achieves the purpose of tightening or loosening the folding handle screw 1; when the folding handle screw 1 does not need to be tightened or loosened, the handle 13 can be folded and stored in the storage groove 121, so as to reduce the volume, which will not affect the normal use of other structures, for example, it will not affect the angle adjustment of the gun barrel, it is extremely convenient to use, and has strong market competitiveness.

The glass bead 141 at the end of the glass bead screw 14 is exposed in the receiving groove 121 and is held and positioned by a first positioning groove 132 provided on the side of the handle 13 received in the receiving groove 121. When the handle 13 is folded and received in the receiving groove 121, the outer wall of the handle 13 contacts the glass bead 141 first, and the glass bead 141 compresses the spring 142 inside the glass bead screw 14. As the handle 13 is continuously pressed in, when the glass bead 141 corresponds to the first positioning groove 132, the glass bead 141 is ejected outwards by the elastic force of the spring 142 and then falls into the first positioning groove 132, thereby positioning the handle 13 so that the handle 13 is stably received in the receiving groove 121 to prevent the handle 13 from accidentally falling out.
