[0032] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] Example 1: As Figures 1 to 7 As shown, a clamp includes: a fixed base 1, a rotating component 2, a clamping component 3, and a plastic bottle 4. The rotating component 2 is disposed on the inner top of the fixed base 1, the clamping component 3 is fixedly connected to the top of the rotating component 2, and the plastic bottle 4 is sleeved on the outer side of the clamping component 3.

[0035] The clamping assembly 3 includes a gear 201, a limiting shaft 203, a locking tooth 204, a spring 205, and a support rod 206. The gear 201 is rotatably connected to the inner side of the fixed base 1. A sliding groove 202 is provided on the inner side of the fixed base 1. The limiting shaft 203 is fixedly connected to the inner side of the sliding groove 202. The locking tooth 204 is slidably connected to the inner side of the sliding groove 202. The locking tooth 204 is slidably connected to the limiting shaft 203 and meshes with the gear 201. The spring 205 is sleeved on the outer side of the limiting shaft 203 and fixedly connected between the locking tooth 204 and the sliding groove 202. The spring 205 pushes the locking tooth 204 to insert into the outer side of the gear 201. The support rod 206 is fixedly connected to the top of the gear 201.

[0036] Clamping assembly 3 includes a support tube 301, a motor 303, a connecting ring 306, a rotating tube 307, a connecting shaft 311, an anti-slip clamping plate 312, a rotating rod 313, and a spring 314. The support tube 301 is fixedly connected to the top of the support rod 206. A motor compartment 302 is provided inside the support tube 301, and the motor 303 is fixedly connected to the inside of the motor compartment 302. Lead screws 304 with opposite thread directions are fixedly connected to both ends of the drive shaft of the motor 303. A limiting groove 305 is provided on the outside of the support tube 301, and the connecting ring 306 is slidably connected to the inside of the limiting groove 305. The connecting ring 306 is threadedly connected to the lead screw 304. The rotating tube 307... 7. A fixed shaft 308 is fixedly connected to the inner side of the rotating tube 307 and the outer side of the connecting ring 306. A pressure sensor 309 is fixedly connected to one end of the fixed shaft 308. A connecting groove 310 is opened on the outer side of the support tube 301. The connecting shaft 311 is slidably connected to the inner side of the connecting groove 310. An anti-slip clamp 312 is fixedly connected to one end of the connecting shaft 311. A rotating rod 313 is rotatably connected to the inner side of the anti-slip clamp 312. The rotating rod 313 is slidably connected to the fixed shaft 308 and the rotating tube 307. A spring 314 is sleeved on the outer side of the fixed shaft 308 and fixedly connected between the rotating rod 313 and the pressure sensor 309.

[0037] In practical use, the plastic bottle that needs to be cooled and sprayed is placed on the outside of the support tube 301. The motor 303 is started, so that the drive shaft of the motor 303 drives the lead screw 304 with opposite thread directions at both ends to rotate. The lead screw 304 drives the connecting ring 306, which is limited by the limiting groove 305, to move within the limiting groove 305, so that the top and bottom connecting rings 306 move closer to each other. The rotating tube 307 and the rotating rod 313 rotate, pushing the anti-slip clamp 312, which is limited by the connecting shaft 311, to expand outward at the same time, supporting and clamping the plastic bottle 4 from the inside.

[0038] As the anti-slip clamp 312 continues to move closer to the inner wall of the plastic bottle 4 and the connecting ring 306, the rotating rod 313 begins to slide inward toward the rotating tube 307, squeezing the second spring 314. The second spring 314 transmits the pressure to the pressure sensor 309, which can monitor the clamping force in real time. When the monitored support clamping force reaches a preset value, the pressure sensor 309 can control the motor 303 to stop rotating, so that the anti-slip clamp 312 locks the plastic bottle 4, allowing the plastic bottle 4 to be cooled.

[0039] When plastic bottle 4 needs to be selected and fully sprayed, simply rotate the support rod 206. The support rod 206 drives the gear 201 to rotate. When the gear 201 is subjected to a large rotational force, the gear 201 can push the retaining tooth 204 to retract into the inner side of the slide groove 202. After the gear 201 rotates to the appropriate spraying angle, stop rotating the gear 201. The spring 205 rebounds and pushes the retaining tooth 204 to re-engage the outer side of the gear 201, locking the gear 201 and preventing accidental rotation during the processing and spraying of the plastic bottle 4.

[0040] The pressure sensors are all existing products on the market, and their connection methods and control methods are all existing technologies, so they will not be described in detail here.

[0041] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
