[0002] Caulking gun is a bonding, sealing and caulking tool, which is widely used in building decoration, electronic appliances, automobiles and automobile parts, ships and containers and other industries. Glue guns can be divided into three types: manual glue guns, pneumatic glue guns, and electric glue guns. At present, when injecting glue, it is generally held by hand, the glue gun head is aimed at the part that needs to be sealed, and the fingers press the glue gun. The tighter the fingers press, the faster the glue will be discharged.

[0003] For example, Chinese patent CN202022725302.9 discloses a manual glue squeezing gun, which includes a gun body, a push rod assembly and a feeding mechanism arranged in the gun body, wherein the push rod assembly is inserted into the feeding mechanism; the manual glue squeezing gun also includes: a wrench assembly, wherein the wrench assembly is connected to the feeding mechanism, wherein the wrench assembly drives the feeding mechanism to move, thereby driving the push rod assembly to move; a positioning member, which is arranged at a position where the wrench assembly is close to the feeding mechanism, and when the feeding mechanism moves in the direction of glue squeezing, the feeding mechanism is restricted in the gun body. The utility model restricts the feeding mechanism by setting the positioning member, thereby replacing the restrictive effect of the protective cover in the prior art, so that the overall cost of the glue squeezing chamber is low, the economy is good, and the weight is light, and it is easy to use.
