A timed glue gun includes a glue pushing unit including a trigger, a glue pushing member and a heating member for melting the hot melt glue stick, and a control unit including a timing member and an alarm member. The trigger is at a released position, and is operable to be pressed to a triggered position. The timing member starts to count upwards from zero when the heating member starts to heat up, and controls the alarm member to emit a first alarm signal when counting to a first elapsed time. The alarm member emits a second alarm signal when the timing member counts to a second elapsed time longer than the first elapsed time in response to continuous location of the trigger at the released position for the second elapsed time during heating of the heating member.

The present application provides a hot melt gun including a housing having a cavity, a heating assembly mounted within the cavity and a connecting rod, wherein the housing is provided with a first through port; the heating assembly extends out of the housing from the first through port; and the connecting rod is a poor conductor of heat, and both ends thereof are respectively connected to the housing and the heating assembly, and the heating assembly is spaced apart from the housing. According to the hot melt gun provided by the present application, the heating assembly is spaced apart from the housing, a poor conductor of heat is selected as a connecting rod, the heating assembly is connected to the housing, the overall structure is simple and stable, the heat generated by the heating assembly during processing directly acts on the glue stick.

A method of repairing a first automotive part that includes providing a connector tab and applying a fluidic thermoplastic material to the connector tab and/or the first automotive part to attach the connector tab to the first automotive part. The connector tab comprises: a retainer portion sized to attach to the first automotive part, wherein the retainer portion has a plurality of holes formed therethrough, and wherein the plurality of holes is configured to receive the fluidic thermoplastic material to secure the retainer portion to the first automotive part; and a coupler portion defining a shape corresponding to a portion of the first automotive part, the coupler portion forming a coupler, which is configured to operably engage another coupler of a second automotive part.
