The utility model relates to the technical field of clamps, and particularly discloses a pneumatic clamping tool which has the advantages that the clamping force is perpendicular to the clamping surface of a product, the clamping force is controllable, the product is clamped stably and is not easy to damage, the operation difficulty is low, and the working efficiency is high. Comprising a first clamping jaw and a second clamping jaw which are oppositely arranged, a first handle located in the same plane with the first clamping jaw and fixedly connected with one side face of the first clamping jaw, and a sliding table air cylinder located between the first clamping jaw and the second clamping jaw, a grabbing and clamping area used for clamping products is formed between the second clamping jaw and the first clamping jaw, and the sliding table air cylinder comprises a cylinder body fixedly connected with the upper surface of the second clamping jaw and communicated with an external air pressure device and a sliding rod inserted into the cylinder body in a sliding mode and fixedly connected with the lower surface of the first clamping jaw. The lower surface of the first clamping jaw and the upper surface of the second clamping jaw are perpendicular to the height direction of the cylinder body, and when air pressure in the cylinder body changes, the sliding rod drives the first clamping jaw to move so as to adjust the height of the grabbing and clamping area.

An online dry powder bag leak detection device includes: an adjustable clamp, a spacing positioning component, a pressure gauge, a pressure tube, and a pressure tapping tube. The adjustable clamp includes first and second pressure plates arranged in parallel, connected by an adjustable connector, and the spacing between the two pressure plates is adjustable. A slot is provided on the first pressure plate. The online dry powder bag is placed between the two pressure plates, with the online connector located in the slot and protruding upwards from the first pressure plate. The spacing positioning component includes a positioning body and spacing positioning platforms of different thicknesses disposed on the positioning body. The spacing positioning platforms can be inserted between the first and second pressure plates to position the spacing between them. One end of the pressure tube is connected to an external air source, and the other end is connected to the liquid inlet pipe of the online connector. One end of the pressure tapping tube is connected to the liquid outlet pipe of the online connector, and the other end is connected to a pressure sensor. This invention improves the accuracy and ease of operation for leak detection of online dry powder bags with welded online connectors.

The invention discloses a quick-release lock which comprises a lock plate, a lock body and a lock sleeve, the lock sleeve is arranged outside the lock body in a sleeving mode, an elastic lock pin assembly is arranged at the upper end of the lock body, a push block return assembly is arranged in the lock body and arranged below the elastic lock pin assembly, a retractable inserting hole is formed in the elastic lock pin assembly, and a lock pin safety buckle is arranged on one side of the retractable inserting hole. The lock body is provided with a sliding block capable of moving up and down, the sliding block is connected with the lock sleeve, a second spring is connected between the sliding block or the lock sleeve and the lock body, the lock plate is used for being inserted into a retractable inserting hole of the elastic lock pin assembly and pushing the push block return assembly into the lock body, and the elastic lock pin assembly retracts through the retractable inserting hole to lock the lock plate. The sliding block is used for moving upwards to be inserted into the lock pin safety buckle of the elastic lock pin assembly, and the retractable insertion hole is prevented from expanding and returning. According to the quick-release lock, one-step connection with one hand and two-step release with one hand can be achieved, and the work efficiency and safety of the quick-release lock are improved.
