A compact, portable in-line heat press machine that holds the upper heated platen horizontal and laterally aligned with the lower platen is provided. The lower frame has front and rear pivot joints on each side of such frame to accommodate linkage arms pivotally attached to it and the upper frames which has similar pivot joints. As such the upper heated platen is lifted up and straight back with respect to the lower platen assembly which completely clears the lower platen for unobstructed loading/unloading of lower platen while keeping the upper platen assembly in a horizontal position. When the upper platen is moved into the lower position, a locking mechanism affixes the upper and lower platen assemblies so that the platen actuators can cause a linear movement between them thus causing a pressing action.

A heat press includes a clutch and a linkage that moves the upper platen relative to the lower platen from a first position to a second position. The distance between the upper and lower platen is less in the second position than in the first position. The clutch is coupled to the linkage and mounted to the upper platen. The clutch is configured to adjust the distance between the upper and lower platens in the second position in response to movement of the upper platen from the first position to the second position being impeded by a work piece positioned between the lower platen and the upper platen.

A writing instrument compressing device includes a base having an underside mounted to multiple raiser pieces to have the base separate from a carrying surface by a distance in a vertical direction. The base includes an elongate hole that is delimited by two opposite sidewalls each including tooth ridges and the tooth troughs alternately arranged. A handle rod is pivoted to an end of the base to drive reciprocal movement of a pusher. A retainer is reciprocally movable along the elongate hole of the base and functions to clamp and fix a writing instrument body or a tool. The retainer is provided, on a bottom thereof, with a screw rod extending through the elongate hole of the base. A tightening assembly includes a nut and a rotation bar horizontally penetrating through the nut and having two ends selectively moved close to the nut.

A heat press includes a clutch and a linkage that moves the upper platen relative to the lower platen. A first link is pivotably coupled to the base and pivotably coupled to an intermediate link. The intermediate link can rotate in a first rotational direction from a first rotational position to a second rotational position. A first clutch member can be coupled to the intermediate link. A second clutch member can be mounted to the upper platen for common movement with the upper platen. When the intermediate link is in the first rotational position, the clutch can be disengaged to permit relative movement in the clamping direction between the first and second clutch members. When the intermediate link is in the second rotational position, the clutch can be engaged to inhibit relative movement between the first and second clutch members.

A pen assembling press includes a base, a press unit, a carriage, and a positioning arrangement. Actuation of a lever moves an engagement head relative to the base along an actuation axis. A second engagement head is coaxial with the first engagement head. The carriage is movably mounted to the base. The positioning arrangement includes a slot, a plurality of recesses and a pin. The slot extends through the first leg in a direction perpendicular to the actuation axis. The slot has a constant height section having a height. The pin has a shaft and a head. The head is receivable in the recesses. The shaft has a thickness being substantially equal to the height of the constant height section of the slot. The pin is movable relative to the carriage along a pin axis that is perpendicular to the actuation axis to selectively engage and disengage the recesses.
